    • A fuel-injected internal combustion engine wherein fuel is injected in dependence upon a quantity or volume of air supplied to the engine. A throttle valve controls the airflow rate with an O.sub.2 probe, arranged in an exhaust manifold, controlling a timing valve through a control device for enabling a timed relief of injection pressure of the fuel. An ignition starter switch is connected to the control device in such a manner that the timing valve is fully open during an operation of the ignition starter switch so as to enable a starting boost. An adjustable timing member is coupled to an operating switch provided in the control device, which operating switch closes automatically after a termination of the starting process. The timing member maintains the timing valve in a fully open position during a specific time span so as to provide for an after-start boost. An additional timing member is adapted to maintain the timing valve in a fully open position during a short time span so as to enable an acceleration enrichment. The control device renders the start boost, after-start boost, and acceleration enrichment ineffective upon the probe reaching its normal operating temperature.
    • 燃料喷射的内燃机,其中根据供应给发动机的空气的量或体积喷射燃料。 节流阀通过配置在排气歧管中的O2探头来控制气流速度,通过控制装置控制定时阀,以便定时释放燃料的喷射压力。 点火开关开关以控制装置的方式连接到控制装置,使得定时阀在点火起动开关操作期间完全打开,以便启动增压。 可调定时构件联接到设置在控制装置中的操作开关,该操作开关在起动过程终止之后自动关闭。 正时构件在特定时间跨度内将定时阀保持在完全打开位置,以便提供后启动增压。 附加的定时构件适于在短时间段内将定时阀保持在完全打开位置,以便能够加速富集。 控制装置提供启动升压,启动后升压和加速浓缩对探头达到正常工作温度无效。
